Detection of loss in electrical distribution networks

摘要

The invention proposes a method for detecting loss in an electrical distribution network. The method comprises a step of receiving average measured voltage values and average measured current values associated with one or more points of supply within the electrical distribution network, and a step of receiving average measured voltage values and average measured current values associated with a plurality of points of consumption within the electrical distribution network. Furthermore, the method comprises the step of calculating conductivity paramters based on said received average measured voltage values and average measured current values and the step of receiving further average measured voltage values and average measured current values associated with said points of supply within the electrical distribution network. Still further the method comprises the steps of receiving furher measured average voltage values and average current values associated with said points of consumption within the electrical distribution network and analyzing said further received average measured voltages and average measured currents using said calculated conductivity paramters to detect any deviations of measured currents values from calculated currents values with respect to a given point of consumption or point of supply.
